and because we would float off into space
friction is one of the most important phenomena in the universe... w/o friction life on earth would be impossible.... we can walk due to friction because earth offers resistance to the motion of our feet thus applyin reaction to uor action of applying force to the earths surface and propelling us forward... this is just one example an we need friction in almost every activity..........

Gravity is the only force that makes raindrops fall to Earth, so itmust also be the one most responsible for that phenomenmon.
Our most important energy is the force of gravity, which heats the inside of the Earth and keeps its surface habitable. The Sun's heat and light are the next most important.
Without friction air is controlled by pressure differences and the rotation of the earth. Friction slows down the air movement while the pressure source remains the same.
Most certainly for without friction the braking system would fail no matter how much force was applied.
Yes, friction exists whenever two objects touch. Friction is caused by two effects: direct contact of mechanical surface irregularities and the electromagnetic force. It has nothing at all to do with the gravitational force, the strong force, or the weak force.
Presumably the most important force on an accelerating space shuttle is the force of the rocket engines (thrusters). Certainly other forces are present, including gravity and air friction.
a car driving on the road
In any given case, friction can produce AT MOST a certain amount of friction; if the coefficient of friction is known, this can be calculated as the normal force multiplied by the coefficient of friction.The force necessary to move an object must, of course, be greater than this maximum friction.
Friction and Air Resistance
One of the most important frictional forces to humans is the static frictional force that the ground exerts on a body. Without this force, walking would be impossible, cars would go nowhere.
